MILK STIRRING AND COOLING DEVICE Filed March 26, 193 5 I 2 Sheets-Sheet2 Patented May 26, 1936 UNITE STATES 1 Claim.

This invention relates to a device for cooling milk and for storing thesame while it is being cooled to promote rapid cooling of the milk.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein:

Figure 1 is a sectional view illustrating the invention.

Figure 2 is a top plan view of a chamber forming part of the invention.

Figures 3 and 4 are detail views taken substantially on the lines 33 and4-4 respectively of Figure 2.

Figure 5 is a pivoted water receptacle.

Figure 6 is a perspective view of an agitator. Referring to the drawingsby reference numerals it will be seen that the invention comprises awater tank 5 having metallic side walls, a bottom wall 6 of wood orother suitable material, lined with a sheet I of metal or the likehaving down turned flanges fitting snugly between the edges of thebottom 6 and the side walls of the tank. Also for the tank there isprovided a removable lid 8 having an opening 8a. with which is alignedone end of a water supply pipe 9, and a slot ID in which operates aflexible element, in the present instance, a chain II.

The chain II at one end is suitably connected with the upper edge of awall of a Water tank I2. The water tank I2 is mounted on a pivot I3extending between opposed walls of the chamber or tank 5, whereby thetank I2 is mounted to swing vertically within the chamber or main tank5. Adjacent the bottom thereof, the front wall of the tank 5 is providedwith a discharge opening from which extends a spout I4.

In the region of the spout I4 there is secured to the bottom 6 of thetank 5 an inverted U-shaped clamp member I5 one leg of which is providedwith a clamping screw I6.

A cooling tank I8 of suitable capacity is adapted to have the edge ofone wall thereof secured by the clamp I5, the screw I6 binding one wallof the coolingtank I8 against the free leg of the clamp I5 as clearlyshown in Figure 1. Adjacent its open top the cooling tank I8 is providedwith an overflow pipe l9 leading therefrom. It will thus be seen thatthe cooling tank I8 is so secured relative to the tank 5 that water fromthe tank 5 discharging through the nozzle I4 will pass into the coolingtank I8 and around the milk pail 26 located therein for cooling thecontents of the pail 20.

For stirring the milk contents of the pan 20 there is provided anagitator in the form of a rod 2| provided on one end with a head 22 inthe form of a disk as shown. At its upper end the rod 2I is formed withan eye or otherwise provided for connection with the free end of the 5chain or flexible element 1 I.

The chain or flexible element II is trained over suitable pulleys orsheaves 23 mounted in brackets 24 secured to the top wall or ceiling ofthe room in which the apparatus is located and 10 as clearly suggestedin Figure 1.

In operation, the parts are normally in the position shown in full linesin Figure 1. To cool and stir the milk incidental to the coolingthereof, water from the pipe 9 empties into the recepl5 tacle I2 andwhen a suitable water level is reached in the receptacle I2, the latteris caused to swing about its pivot I3 from the full line position shownin Figure 1 to the dotted line position shown in said figure. Theswinging of the 20 receptacle I2 in this manner will exert a pull on thechain II causing the stirrer rod 2| and its head 22 to move upwardly foragitating the contents of the pail 20.

Obviously, when the receptacle 20 upsets in the 25 manner justmentioned, the water contents thereof will flow therefrom and throughthe spout It to empty into the tank I8, the water filling the tank andserving to cool the milk contents of the tank 20. 30

When the receptacle I2 is thus emptied of its water contents the sameunder weight of the agitator will be caused to swing back to the fullline position for receiving another charge of water from the pipe 9.Upon swinging movement of 35 the receptacle I2 from the dotted. lineposition to the full line position, the stirrer rod 2| and its head 22will move downwardly toward the bottom of the milk pail 26. Thus it willbe seen that a reciproca'tory movement is imparted to the stirrer foragitating the milk contents of the pail 20, as said contents are alsobeing cooled by the circulation of water through the tank I8, the wateras before mentioned entering the tank from the spout I4 and overflowingfrom the tank through 45 the overflow I9.

Having thus described the invention, what is claimed as new is:

In a device of the character described a tank adapted to receive acooling fluid, and a con- 50 tainer the contents of which are to becooled, a second tank having adjacent one side thereof U- shaped bracketmeans adapted to straddle the wall of the first tank and screws carriedby said U-shaped bracket means for clamping engage- 2 A I 2,042,108 rment with said wall of the first tank, said second tank having at saidone side thereof a discharge nozzle arranged to direct fluid into thefirst tank, a receptacle for the cooling fluid pivotally mounted in thesecond tank for vertical swinging movement and arranged to discharge thecontents thereof into the second tank for passage from the second tankinto the first named tank, sheaves adapted to be secured from a ceilingor suitable tacle whereby the swinging movement of said 5 receptaclewill cause the stirring device to be raised and lowered within thecontainer the contents of which are to be cooled.
